Final answer:
The surface area formula for a right cone is different from the surface area formula for an oblique cone.
Step-by-step explanation:
The surface area formula for a right cone is different from the surface area formula for an oblique cone.
For a right cone, the surface area formula is πr(r + l), where r is the radius of the base and l is the slant height.
For an oblique cone, the surface area formula is π(r + R)l, where r is the radius of the smaller base, R is the radius of the larger base, and l is the slant height.
